Captain America is back to fight his arch nemesis. The Red Skull. The Red Skull and Captain America have been fighting for decades. Their fights will likely never end, but what counts in the end is whose stronger. Captain America has the Super Soldier Serum and his trusty shield.
Of course Red Skull also has superhuman strength and superhuman speed. With the Cosmic Cube Red Skull’s abilities were amped up even further. Cap usually wouldn’t have a chance against a Cosmic Cube wielder, but with Mjolnir at his side Cap won’t lose. He’s come too far in this blog to take a loss now. Captain America wins.
